#emberjs

Hey guys, I’m getting an error upon build and I’m not sure how to fix / what’s the root cause. I’m currently getting: ConcatWithMaps: nothing matched [ligef/**/*.js]

Error: ConcatWithMaps: nothing matched [ligef/**/*.js]

I tried setting locationType: 'auto', in config/environment.js which solved it for the current instance, but when I restarted ember server I get it again and can’t get past it

when I hit the home route I get: ENOENT: no such file or directory, scandir 'undefined/'

Vip3rousRX: what is "ligef" ?

that is the name of the app

hmm… setting locationType: ‘none’ just fixed it while the server was running, my page loads now...

but, i don’t have a clue why?

is there a good way to take an adapter error at the model level and decide to continue to render, except with something different, like an error template or error component or something?

I can handle this by transitioning to a different route, but I think it’s a poor user experience for someone to lose the URL they typed

hi everyone, I'm trying to learn ember but I'm stuck on creating my first app with ember 2.3

er and sorry, I meant adapter error at the route level

alxlopez, just tell us where you are stuck

I was following the instructions but when I checked ember version the console display 1.3

alxlopez, you'll want ember-cli beta

and if I change in bower.json to use ember 2.3.0 and run bower install it shows me errors

alxlopez, https://github.com/ember-cli/ember-cli/releases...

joshsmith: https://guides.emberjs.com/v2.3.0/routing/loadi...

Gandalfar: you can do `npm install -g ember-cli@beta`

alxlopez: ^

ok I'm going to try this

alexspeller: isn’t this transitioning?

thanks

alexspeller, awesome, thanks :)

joshsmith: I'm not sure what you mean by that question

alexspeller, I think this #1 question here, it should really be in the 2.x guides

what you linked in the guides shows a transition to an error page

joshsmith: as far as I can tell, the error substate is exactly what you're looking for

joshsmith: you asked "decide to continue to render, except with something different, like an error template"

joshsmith: that's what error substates do

Gandalfar: yes, I agree it's very very bad that the default ember install installs an old version of ember

alexspeller, does it makes sense to add a note about this in the guides?

ah

but is in the guides

Gandalfar: it's been that way for months, due to semver issues. Personally I'd argue that a good on-boarding experience is more important than semver issues but that's not the decision that's been made

nevermind then

people just don't read

alexspeller: I see, but it doesn’t look like that ever gets hit, I just get an “Adapter operation failed” error because of a 404

joshsmith: what did you try to implement the error substate?

joshsmith: here's a simple example https://ember-twiddle.com/effde4fa35977ea62c8f?...

just created a templates/route-name/error.hbs

nothing at all renders, though. the app just errors out

joshsmith: is the loading error in the "route-name" route?

yes, if I debug into actions: error, you can see there’s an ember$data$lib$adapters$errors$$AdapterError

joshsmith: that won't work

joshsmith: routes are heirarchical. You can't enter route-name/error if there is an error in route-name loading because you'd have to enter route-name first

alexspeller: re: stuff discussed earlier. I'm wrapping my array items with a checked attribute. Is an ArrayProxy the correct way to go about doing that?

so it would have to be handled at application-error then?

joshsmith: your error template / route has to be a sibling of the route where the error occurs

I’m confused, because it appears that the error is occurring in the “route-name” route I mentioned

dhdemerson: I don't see where an array proxy would help you

joshsmith: yes, that's the case

dhdemerson: a plain array is all you need

alexspeller: Using the "objectAtContent" to add the checked attribute to items

dhdemerson: [{item: someItem, checked: false}, {item: someOtherItem, checked: true}]

alexspeller: Where do I make that array? In the component? If so how do I access the model from there? Do I put it in a computed property?

dhdemerson: make the array at the highest point in your heirarchy where the data is needed

dhdemerson: maybe that's a component, maybe a controller, or maybe you want to store it in a service if it's more global

so alexspeller maybe this is something that can be clarified in docs? I thought that templates/route-name/error.hbs would work, but templates/route-name-error.hbs was what actually worked

joshsmith: https://guides.emberjs.com/v2.3.0/routing/loadi... shows the naming of the error templates like that

is this a misunderstanding on my part, or are the docs suggesting that would have worked?

according to that it seems like templates/route-name/error.hbs should have worked

joshsmith: nope, it says "articles.overview-error" not "articles.overview.error"

fwiw I think that page could use some love, but it does seem to be correct to me

alexspeller: but it does say “articles.error”

or “articles-error”

joshsmith: yes, that will also work for errors in the articles.overview route

oh wait, I think I see what I’m missing

yeah, this is really confusing

I see what you meant in the way you explained it, but the way it is explained here in the docs does not clarify it the same way

joshsmith, https://www.youtube.com/watch?v=Dp57YdJPWx4 good talk on this subject

thanks Gandalfar

I touch on substates in that talk, I'm doing a more in-depth talk at ember global meetup on the 5th Feb

will that be recorded?

it will be solely about error and loading substates

yes

excellent

joshsmith: but if you didn't know it's a live global streamed event, not a physical meetup

joshsmith: https://www.bigmarker.com/communities/global-em...

I’ve been way out of the Ember run loop for awhile, sadly

wait, I think it's the 6th of Feb

yeah, it’s the 6th

it’s okay, I can sit in line for a day
